Abstract
The facsimile recording machine having a loop electrode which moves along its own locus, a portion of which includes a linear track. The linear track is opposed by a scanning electrode, between which, a printout is produced on a web.The linear track in which the loop electrode moves is transversely adjustable towards and away from the scanning electrode and also includes a lubricious member therein which holds the electrode moving therepast, in a linear path, free of vagaries and against one side of the linear track.
Claims18
Apparatus for recording grahic signals on a web by electrical erosion of metal ions from an electrode, the apparatus comprising:
- an electrode with sides extending to a recording edge;
- means for moving the electrode on a linear path across the web;
- linear guiding means engaging both sides of the electrode to hold the electrode straight on said path, the recording edge of the electrode eroding toward the guiding means,
- and adjusting means including a manually adjustable pusher on the guiding means engaging the electrode, the pusher being manually adjustable from an initial position, in which it holds an unworn electrode at an initial extent from the guiding means, to an adjusted position outward of the guiding means in which it pushes a worn blade to the same extent thereby to compensate for erosion of the electrode.
